摘要:
An oral care implement, such as a toothbrush. In one embodiment, the invention can be an oral care implement comprising a handle and a head. A plurality of tooth cleaning elements may be provided on a front surface of the head. The head is formed by a plurality of spaced-apart segments formed of a rigid material. The segments are isolated from one another by channels containing an elastomeric material that flexibly connects the segments together. The oral care implement further comprises an elastomeric soft tissue cleaner located on a rear surface of the head opposite the front surface of the head. The elastomeric soft tissue cleaner comprises a plurality of grooves that are aligned with the channels.

摘要:
An amplifier circuit includes a pair of transistors amplifying differential signals of input signals to respective input terminals and outputting differential output signals to respective output terminals, and an impedance circuit provided in between sources of the pair of transistors, canceling a first cutoff characteristic on a high frequency side in frequency characteristics of the amplifier circuit constructed of the pair of transistors, and forming a second cutoff characteristic on a higher frequency side than the first cutoff characteristic.
摘要:
A process for coating an article made of tantalum niobium or tantalum-niobium alloy with a film containing polycrystalline lithium metal oxide wherein the metal corresponds to the metal from which the article is made. More particularly, the process improves the surface properties including hardness, yield strength, elasticity and electrical properties so that the operating life can be increased and new application for such articles can be made.It is found that tantalum spinnerets treated in accordance with the process according to the present invention have longer operating life, clog less and produce a better quality fiber.

An oral care implement, such as a toothbrush, comprising a flexible head formed of a plurality of flexibly connected segments. In one embodiment, the invention can be an oral care implement comprising a handle and a head. The head can be formed by a plurality of spaced-apart segments constructed of a rigid material and separated by a channel containing an elastomeric material. An elastomeric cleaning element comprising, a base portion and an upper portion extends form a front surface of the head. The elastomeric cleaning element extends from and is connected to the elastomeric material of the channel so that the base portion overlies a portion of each of the front surfaces of the segments on opposing sides of the channel. In another embodiment, the invention can be the elastomeric cleaning element itself, irrespective of the type of head in which it is incorporated. In yet another embodiment, the base portion can be tapered.

An oral care implement, such as a toothbrush. In one aspect, the invention is an oral care implement comprising a handle and a head. A plurality of tooth cleaning elements may extend from a front surface of the head, which is formed by a plurality of spaced-apart segments formed of a rigid material, wherein the plurality of segments include a cruciform segment integrally formed with and extending from a distal end of the handle, a first pair of segments located on opposite sides of a longitudinal portion of the cruciform segment, and a second pair of segments located on opposite sides of the longitudinal portion of the cruciform segment, the first pair of segments located on an opposite side of a transverse portion of the cruciform segment from the second pair of segments. The segments of the first and second pairs are flexibly connected to the cruciform segment.
